Consider fit LinearRegression
| fit LinearRegression "name2predict" from "f1" "f2" into "test_model"
What are flexebilities defining the FEATURE LIST -- i.e. from "f1" "f2" ?
Is it possible to write something like
NOT "f1" - exclude "f1"
or something like f1* OR f2*
SubQuestion 2 Can we use somehow subsearch to generate fields list ?
If no simple way to do it what are some ways round ?
If you wanted to exclude
f1 then you should not include it as your explanatory field.. Why would you want to choose
f2? Why not just include both and let the machine determine which feature to put emphasis on? You can run
| summary <model_name> to identify how much impact each feature has on the target function.
Why do you mean using a sub-search to generate a fields list? Are you referring to making the data available so you can fit your model? If so, then you can use whatever you want just as long as the data is available before the
fit command. One thing to consider though is speed and scale. You need to make sure your search is fast so it can run on a consistent basis so the machine can keep learning and adapting
To make explicit description of fields names is very inconvenient in my case, because that names can be changed. I want to exclude very specific name like "_time" , but I do not want to exclude by previous "field - _time" command, because then it will dispappear from the whole pipiline, so it would be impossible to plot by next command "table _time, error". By using subsearch I mean something like [ | mcatalog | return ??? ] put such expression instead of explicit fields list.
